Integrated concept for plant instrumentation

All field instruments in one packageField instruments are an essential part of any plant and have a crucial impact on proper functioning. However, newly designed facilities are often equipped with field instruments from various suppliers, requiring a substantial coordination effort from the customer: Quotations have to be obtained and compared, orders have to be tracked and deliveries checked. This demands a lot of resources from the cus-tomer and creates an exceeding number of interfaces.

One partner for all your requirementsVoith offers a large variety of valves and sensors. The cus-tomer thus saves resources and benefits from the knowl-edge of Voith experts as well as partnerships with leading technology companies. Thanks to the different variants pro-duced exclusively for Voith, the best possible solution can be selected for each process segment.

Voith’s extensive process and application know-how ensures an optimal equipment selection according to the customer’s needs. After compiling a portfolio of field instruments, all subsequent steps up to commissioning of the products can be handled by Voith. In addition, delivery times and consis-tently high product quality are guaranteed.

Voith offers an integrated solutions package for your plant instrumen tation. Customers therefore benefit from simplified order processing, leaving the entire instrumentation handling to Voith. This ensures flexible on-time delivery, adapted to the customer’s actual needs.

10. OnC LevelSens Level measurement for harsh environments

Application This sensor measures levels of media such as water, steam, fiber suspensions, coating colors and chemical additives. OnC LevelSens 200 series uses radar to measure the level of suspensions, liquids or bulk materials in challenging applications. Extremely short microwave pulses are radiated from the antenna system onto the product to be measured, reflected by the surface and then received again. The distance, and therefore the level, are calculated from the time elapsed for this process. Interference signals are reliably balanced by electronic means, so that there is no need to calibrate with the vessel in full and empty state. The OnC LevelSens 300 series uses ultrasound and transmits short ultrasonic pulses of up to 70 kHz to the surface of the product. The distance and level are calculated from the time elapsed. In capacitive measurement, as used by the
